Merge tag 'gpio-updates-for-v6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski: "Here are the updates for this merge window from the GPIO subsystem. We have more lines removed than added thanks to dropping of a driver for a platform that's no longer supported. Otherwise the changes are pretty straightforward: support for some new models, various improvements to existing drivers, some tweaks to the core library code and DT bindings updates. Summary: - remove gpio-vr41xx driver as the only platform using it got dropped too - add support for suspend/resume to gpio-davinci - improvements to the GPIO character device code - add support for disabling bias for in-kernel users (up until now only user-space could set it) - drop unused devm_gpio_free() - fix a refcount issue in gpiolib OF - use device match helpers where applicable - add support for a new model to gpio-rockchip - non-functional improvements in gpio-adp5588 - improve and simplify teardown in gpio-twl4030 and gpio-ucb1400 - modernize the gpio-74xx-mmio and gpio-adnp drivers - coding style improvements in gpio-xilinx, gpio-104-idi-48 - support new model (pca9571) in gpio-pca9570 - convert the DT bindings to YAML for gpio-mvebu and update the document - don't return error codes from remove() in gpio-brcmstb - add a library for the intel 8255 PPI interface and use it in drivers - reduce using magic numbers and improve code readability in several drivers - convert DT bindings to YAML for gpio-tpic2810 - add new models to DT bindings for gpio-frl-imx - Kconfig improvements - other minor tweaks and improvements" * tag 'gpio-updates-for-v6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (52 commits) dt-bindings: gpio: fsl-imx-gpio: Add i.MXRT compatibles gpio: 74xx-mmio: Use bits instead of plain numbers for flags gpio: xilinx: add missing blank line after declarations MAINTAINERS: Update Intel 8255 GPIO driver file list gpio: gpio-mm: Implement and utilize register structures gpio: 104-idi-48: Implement and utilize register structures gpio: 104-dio-48e: Implement and utilize register structures gpio: i8255: Introduce the Intel 8255 interface library module gpio: 104-idio-16: Implement and utilize register structures gpio: ws16c48: Implement and utilize register structures gpio: remove VR41XX related gpio driver dt-bindings: gpio: add pull-disable flag gpiolib: acpi: support bias pull disable gpiolib: of: support bias pull disable gpiolib: add support for bias pull disable gpio: 74xx-mmio: use bits.h macros for all masks gpio: 74xx-mmio: Check MMIO_74XX_DIR_IN flag in mmio_74xx_dir_in() gpio: 74xx-mmio: Make use of device properties gpiolib: cdev: compile out HTE unless CONFIG_HTE selected gpiolib: cdev: consolidate edge detector configuration flags ...
